Myths about Superjet

This article is created based on sitehttp://superjet.wikidot.com/and is designed to appease the mass hysteria over the new Russian Sukhoi Superjet 100 on the Internet.

The first myth — engines of vacuum cleaners.

 

History of Myth

Opponents of the project SSJ100 made statements about the impossibility to use the Superjet 100 in connection with the engines located under the wings, for example:

"Due to the low-lying aircraft engines, on the conclusion of the Ministry of Transport of Russia and the study of TsAGI, requires additional measures to ensure the safe operation of regional airports in Russia. The position is even tougher CRI GA — SSJ 100 can take no more than 5% (!) Airports of our country … Additional measures may be different. From bathing strips and taxiways before each "supersamoletom" on all of his "earthly" way (which is unlikely) to raise the engine up, that is, changes in the structure of the aircraft. "

Theory

From the point of view of the layman the height of the engine — the only thing that determines the likelihood of foreign objects into the engine. Specialists have a different opinion:

Mostly foreign objects and particles in the gas-air compressor is:

  • during taxiing, takeoff, and run out the front and the main landing gear wheels;
  • from gas streams with late closing of the valves reverse thrust on landing aircraft;
  • when the engine is in the parking lot because of a vortex rope under the air intake on the runway.

And, in fact. Swirling Cord — sweet thing, is destroyed by the wind, or motion to skorossti above 50 km / h On the other hand, hard rubber tires, which supports a ton of aircraft weight, throw out the trash yourself with good quality catapult. So for the Safety of aircraft is not more important than the distance from vozduhozabonika to the runway, and the position of the engine relative to the cone emission landing gear.

The research professionals GSS

 

Design

Naturally, the designer GSS knew about all of these features and incorporate them into the design of the aircraft. The proof of this — Materials preliminary design, safely trapped in the net. The main conclusion in brief: RRJ aircraft belongs to the vortex-free vehicles, vortex throw anything into the engine is not possible.

Practice

The plane, along with their low powered flying is not the first year. As you know, the practice — the criterion of truth, if not the only criterion. So, we must turn to the experience of those who worked directly with the plane and read expert comments.

 

Aerodynamic design turbojet nizkoplan with swept wings and a single vertical tail are all foreign haul aircraft operated in Russia. It should be noted that in 2011, for foreign planes had 89% of Russian companies pasazhirooborota Source

 

Low engine arrangement (about 0.5 m) have 56% of Russian long-haul aircraft (Boeing 737 and other Airbus 318/319/320/321 etc., And the SSJ-100

Boeing 737 — world's most popular narrow-body jet airliner. Today, every 5 seconds flies one aircraft of this type, at all latitudes, in operation since 1968. Many years of successful experience of operating the aircraft in Russia proved the possibility of safe operation of aircraft engines with low-lying on the runway airports in Russia.

 

In particular, the airline "Yakutia" has 2 units of Boeing 737-800, 3 units of Boeing 737-700, and also ordered two Superjet-100.

 

On the other hand, a high engine arrangement (1.65m) (performance characteristics of AN-148) In short-haul passenger aircraft An-148 is not allowed to prevent foreign objects from the runway, forcing undertake appropriate improvements:

 

"According I.Kravchenko, operation of AN-148-100 were noted foreign objects from the runway, but with the airplane people, this problem has been fixed, all the preparatory measures in place, and the previously released planes finalized." (Source)

 

The second myth — drank budget.

 

How much is the budget for the Russian Superjet?

In the press and on many forums there is a perception that "the program Superjet 100 insanely expensive" are called wild and false numbers in the tens of billions of dollars. Program accused almost in the collapse of the Russian aircraft industry and "took all the money."

In practice … have a stable state support of the project on behalf of SGS REG / Saturn, even 204CM project is funded as a residual.

 

If …, yes if the state budget spent on the project VSL were sent, for example, the development and improvement of the project Tu-204/214 …, I think, a positive economic impact for the Russian Federation would have been much more …

 

The truth is that the Superjet 100 has received only 5% of all gosudarstvannyh money allocated to the domestic civil aviation industry. Less than the budget invested in the reconstruction of the Bolshoi or Mariininskogo theaters, less than the construction of trains to Pulkovo Airport.

Superjet 100 program has received only 5% of all budget expenditures for the aviation industry

In the Federal Target Program "Development of the GA before 2015" lists all funded projects: SSJ, MS-21, BE-200, Il-96T-300/400, Tu-204/214/204 SM, Mi-38, Ka-62, as well same SaM-146, SC-93, PS-90A-2, PD-14, etc.

 

The budget for the entire aviation industry is on the FTP 2002-2010 111 billion 808.8 million rubles. (Of course military aviation is not included here)

 

Budget money for the entire aviation industry 2011-2013: 144 billion 118.2 million rubles.

Total for the development of the civil aviation industry for the period 2002 — 2013 allocated 255.9 billion rubles.

We go to the guarantor, watch document "Government Decree of October 15, 2001 N 728" On the federal target program "Development of Russian civil aviation for 2002 — 2010 and for the period up to 2015" (amended 2006 — 2011). "

Scroll down to "Appendix 2 to the number of the federal target program" Development of Russian civil aviation for 2002 — 2010 and for the period up to 2015 "(edition of 2011) funding levels of the federal target program" Development of Russian civil aviation on 2002 — 2010 and for the period up to 2015 "»

Once again, scroll down to "The implementation of RRJ (SSJ-100, SSJ-130NG), an engine SaM146». Enjoying the line "including the federal budget *" and see (billion rubles)

Myth Three — screwdriver assembly.

 

Screwdriver assembly — the non-applicability of the term to the Superjet 100.

First, what is a "screwdriver assembly"?

According to Russell R. Miller «Doing Business in Newly Privatized Markets: Global Opportunities and Challenges», production by this method arises when local parts suppliers offer at a higher price or lower quality than foreign suppliers. Therefore advantageous to organize production under license, using the finished product.

So obrvzom can identify the main criteria for defining the concept of screwdriver assembly:

  • 1. there is no need to make product development;
  • 2. there is no need to test prototypes;
  • 3. there is no need to carry out certification;
  • 4. the country imported a set of parts;
  • 5. the country imported instructions for assembly;
  • 6. there is no need to promote your brand — it is already known.

Try to understand the criteria for items:

  • 1. aircraft developed in Russia by Sukhoi Civil Aircraft;
  • 2. testing of prototypes implemented in the Russian domestic manufacturer;
  • 3. certification of the product by the developer of aircraft, that is, again, Russia;
  • 4. set of parts imported into the country is the only point on which the rest of criticism Superjet program, but the point that we discuss in more detail;
  • 5. instructions for assembly belongs to a Russian company and assembly of the aircraft is performed in that country;
  • 6. brand Superjet not previously existed (unlike Boeing, Airbus or An and Tu).

Thus already on five criteria of the six aircraft Superjet is not equivalent to "screwdriver assembly".

 

Why need foreign components?

The reason for choosing foreign suppliers — not only in a smaller weight or higher system reliability. The main and the main criterion — the possibility of certification of components separately, and systems in the aircraft — at rates EASA / FAA. As well as the ability to create these systems for a reasonable time, money, with a guarantee of quality and price stability. Russian suppliers were neither the first nor the second, nor the third, to ensure not taken. A goal was set unambiguous: the possibility of SSJ certification according to international standards. This is one of the basic principles, if you will, the "cornerstone" of the project, without which it would not have been realized.

For this reason, the air conditioning system is Superdzheta leak detection system: in the Russian air-conditioning systems, it has not been used, but the same "Liebherr" with it for a long time "sign". A certified aircraft in Europe is impossible without this component. And such "nuances" are present in almost every system. The aircraft may be praised for the selection of domestic suppliers, only for the SSJ, market opportunities have been very vague.

 

What percentage of the SSJ has imported parts?

One of the main complaints of critics: Superjet-100 — not "our", because it has a large number of foreign components.

"In SSJ 80% imported parts."

So what amount of foreign components in the SSJ?

Accurate information is not, as the aircraft is a very complex machine and contains a huge number of devices, sensors, systems, etc. Is it possible to apply the concept of "number of components" in this situation? What if UAC million purchase foreign-made screws and set them produced in KnAAPO glider Superzhdeta? Then, with respect to one million bolts glider is one millionth of a cent. Is this not an indication of delusion in the minds of applying such comparisons?

But you can make a comparison in the context of finance. What percentage of the financially Superjet consists of foreign components?

To find out the proportion of imported components, it is necessary to go to GSS official website, select "Quarterly Reports" and find the 3.2.3 in each of them.

Get:

  • In Q3 2011, the share of imports in the supply of materials and products was 61.5%.
  • In Q2 2011, the share of imports in the supply of materials and products was 53.32%.
  • In Q1 2011, the share of imports in the supply of materials and products was 41.1%.
  • In 2010, the share of imports in the supply of materials and products was 53.6%.
  • In 2009, the share of imports in the supply of materials and products was 56.5%.
  • In 2008, the share of imports in the supply of materials and products was 18.2%.
  • In 2007, the share of imports in the supply of materials and products was 55.4%.

As can be
seen, the share of imports is around 50-60%, the figures of 80% is not close.

Data from reports in tabular form.

The 80% MP Mironov announced at a meeting of the Duma. Concerning that on what basis he made such conclusions can imagine that this is the ratio of foreign suppliers of components to the domestic. That is, all of the component suppliers SSJ 80% foreign. But such a comparison against similar imported bolts million to one domestic glider.

List of Companies involved in the production of aircraft Embraer E-Jets (Brazilian competitor SSJ100).

  • Manufacturers of aircraft components Embraer E-Jets
  • Manufacturers of aircraft components Embraer E-Jets

Against the background of our EMB Superjet just superrossiysky. Think about it:

  • ALL ALL designing and testing (static, resource, etc) were conducted in Russian. At Embraer is import.
  • ALL of the fuselage and wing SSJ do in Russia. It is import Embraer, 4 of the 6 "barrel", wing, empennage — do abroad.
  • Composites for SSJ do on VASO at Embraer all imports.
  • Metal for Superjet — Russia, at Embraer and rivets and metal — import.
  • Design cockpit Superjet made Zhukovskaja firm Embraer in all imports.
  • In making the Superjet take part nizhnegorodskie firm (Gidromash, Heat Exchanger, Scat) and Ulyanovsk, all imports from Embraer.
  • The company SCA owns 75% of Russia (a 100% Russian UAC), Embraer is owned by the government of Brazil by 0.3%, while the Brazilian bankers by 33%.

However, everyone believes the Brazilian Embraer aircraft made by the same Brazilian firm. What prevents someone considered SSJ Russian plane? Probably, or stupidity, or partisanship, or proplacheny competitors.

List of Companies involved in the production of aircraft Mitsubishi MRJ (Japanese competitor SSJ100).

List of Companies involved in the production of aircraft Bombardier CRJ1000 (Canadian competitor SSJ100).

We ayrbas Boeing, Embraer, MRJ and CRJ same situation with parts. All aircraft manufacturers put on their ships the best thing on the planet and no one will bother pseudo-patriotic ideas in the style of "put domestic." Little did many domestic or CRP — Aircraft manufacturer never important, it is necessary to make the product, "plane", so much so that it was no worse than the competition! And it is not the task airframe manufacturers to raise the entire industry, it is to never have neither the means nor the time. The task of lifting the industry is important, but it must deal with other structures, not KB and aircraft manufacturers.

Think about what would have happened if not for Superjet put all the best that was in the time of design. And put on a "if only domestic." The answer is very simple: the result would be another Tu-334 plane, nesertifitsiruemy in the west and not sold even in Russia itself.
